ok, I love Rex and I can't stand that Charlie is lying to him about being his Dad. And the fact that he just believed him right away was kind of strange to me (especially when Rex is a PI and Roxy isn't the most honest person). So I was thinking maybe Rex is just playing along while he's really checking it out. Then a couple weeks ago (the day Adrianna left for Paris) he took the fork Charlie used at breakfast and put it in a bag. It was out of nowhere and it hasn't been shown or brought up since. Just wondering what others are thinking.
